Connecting to 2 routers on one laptop at the same time

I'm pretty sure it is possible, but I want to double check to make sure it is. I'm using Windows 7.

I'm going to buy a laptop to be a driver station for a robot. The robot has a standard router that the robot connects to, but I can't get on the internet if I'm connected to it.
If I buy a USB wireless adapter, can I connect to both the robot's router, and to another router that is connected to the internet?

The IPs use different formats (10.28.XX.X for the robot, and 192.168.X.XXX for internet)

As far as I can tell from looking online, it should be possible. Is it?

if the robot is hard coded then you can have them on the same network you will just have to multi home your nic.

Thing is I need to use it at different places too, where I wont have access to change any settings to the internet connected router.

Its going to depend how you have this cabled. You can't directly connect a wireless connection to 2 different wireless routers...although you can use 2 different wireless adapters in your PC.

A non standard and not recommended design is to overlap the networks on the same equipment. This is like using a vlan without vlan tags.

If you were to plug the lan side of the robot router to the lan side of your internet router both networks would overlap. You need to be careful only a single router has DHCP. Then what you do is go into the TCPIP advanced settings for your PC and add a second address. Now you can hook to either SSID and still reach both networks. This can cause some issues for things that blindly broadcast looking for stuff DHCP being the most common example.
